We review the magnetic and orbital ordered states in \cro{} by performing Resonant Elastic X-ray Scattering (REXS) at the Ru L-edges. In principle, the point symmetry at Ru…
Orbital-selective metal skin induced by alkali-metal-dosing Mott-insulating CaRuO
M. Horio, F. Forte, D. Sutter +21
Doped Mott insulators are the starting point for interesting physics such as high temperature superconductivity and quantum spin liquids. For multi-band Mott insulators, orbital se…
Field-induced Orbital Patterns in Ferromagnetic Layered Ruthenates
F. Forte, M. Cuoco, C. Noce
We study the evolution of orbital patterns in ferromagnetic layered ruthenates due to the competition of Coulomb interactions, compressive c axis and orthorhombic distortions in th…

K. von Arx, P. Rothenbühler, Qisi Wang +10
Multi-band Mott insulators with moderate spin-orbit and Hund's coupling are key reference points for theoretical concept developments of correlated electron systems. The ruthenate…
Evidence of electronic states driving current-induced insulator-to-metal transition
V. K. Bhartiya, R. Hartmann, F. Forte +16
On demand current-driven insulator-to-metal transition (IMT) is pivotal for the next generation of energy-efficient and scalable microelectronics. IMT is a key phenomenon observed…
